I have a 2007 GP, just got it a week ago with 63,XXX on it. I didn't notice it at first but there is a slight wobble when I let go of the wheel. When I have a hold of the wheel you cant feel it at all in the hands, or at least I cant. Only feel the wobble when moving, only at 25-40 though, then it smooths out. I also feel a wobble/pulsation during moderate to hard braking. Unbalanced tire maybe? Warped rotor? Or is this a possible suspension sounding problem?
